1996 S420 Hesitation problem
I have a great 1996 S420 with 174000 miles of nearly perfect performance. Yesterday the car started a pretty strong hesitation but is erratic. The car will run perfect then suddenly start hesitating and almost stalling. Speed seems to have no effect i.e. will do it at idle or running down the road at a nice clip. Took it to my mechanic today and says there are NO CODES showing a problem and he is as confused as I am. They are going to replace the fuel filter in the morning only at my insistence....any thoughts guys? how does the car do this and not throw a code?
thanks
